Button Click to Hide Objects or return

[ChrisR]

Hello All,

I'm trying to create a button for my indicator to allow for easy cycling of showing the indicator. The indicator draws lines and text at specific DateTime's. I want to just click a button and remove all objects, than upon clicking again, to show all objects.

I have tried using a bool cycle in the button click function, than checking that bool in OnBarUpdate to return; if true. This does not work.

Is there any method that can accomplish this? I have searched the forum and just am not finding what I need.

Hello ChrisR,

From the button click even handler method, you would need to call TriggerCustomEvent() then for each drawing object set the .IsVisible property.
You could loop through the drawing objects either in your custom collection or the DrawObjects collection.

Thanks, Chelsea.

The following is working, but removing objects from other indicators with similar content in the tag. How can I check if the object owner is the current indicator (this)?

foreach (var drawObject in chartWindow.ActiveChartControl.ChartObjects)
{

if (drawObject is DrawingTool drawingTool && drawingTool.Tag.Contains("Open"))

{

drawObject.IsVisible = HideScript;

}

}

Hello ChrisR,

You could add the objects to your own collection and loop over that collection instead.

Or you could check drawObject.DrawnBy == this.
